API Specification

This section specifies the usage for each API function.

Function arguments for each routine are described as in, out, or inout.

1. in argument means that the parameter value is an input only to the function.

2. out argument means that the parameter value is an output only from the function.

3. inout argument means that a parameter value is an input to the function, but the same

parameter is also an output from the function.

Note: inout parameters are typically input pointer variables in which the caller passes the address

of a pre-allocated data structure to a function. The function stores its results within that data

structure. The actual value of the inout pointer parameter is not changed.

ioctl call(s):

The ioctl call is generally represented by one of the following forms:

UWord16 ioctl(const int *pModuleBase, void cmd, void *pParam);

Description: The ioctl call sets the INTC registers.

Items Separators Convention:

only one of the specified items is allowed

consolidation of items is allowed ( item1 | item2 | item3 )

intersection of items is allowed ( item1 & item2 & item3 )
